1. General.
The DS1 is a time delay switch with an illuminated push button, which
replaces a standard single gang plate switch on a box 16mm deep. The
illumination guides the user to the push button and once this is pressed
the lights under control are switched on for a period from approximately
10 seconds to approximately 10 minutes adjustable by internal
potentiometer.
For situations requiring two-way and intermediate switching DSS's can be
used in conjunction with a single DS1. Section 5 shows how these can be
used in retrofit without wiring modifications and section 2b shows how
they should be wired in new installations.

Set the delay time adjuster on the DS1 to minimum (fully anticlockwise –
see fig 2a) to enable initial testing during commissioning.
Remove the existing light switch and transfer the two wires to the DS1
connecting them to terminals L and SL in either position. If two wires
were connected to either terminal on the original switch they must be kept
together and connected to either L or SL on the DS1.
Do not disturb any earthing wire connected to the wallbox terminal.
Ensure both terminals are tight before screwing the two plate fixing
3
screws supplied home sufficiently to locate the DS1 securely to the wall
box. Turn ON the mains supply.
2b. New Installation of a DS1 and Up to
25 DSS's..
In a new installation the DS1 and DSS's can be wired to give control of a
single lamp load by any of the switches.
This is shown in fig 3.
